Abstract

Copula models are usually used in order to capture multiple default contingent payoffs. As such, this standard approach fails to capture credit curve gamma and cross-gamma impacts arising from non-linear dependency on CDS spreads. Neglecting these impacts lead to unexplained P&L swings for the delta hedged portfolios, as it had been demonstrated during crisis. Our approach retains systemic default feature while taking into account a joint dynamics of credit spreads.

IAQF-Thalesians Seminars

The IAQF-Thalesians Seminar Series is a joint effort on the part of the IAQF (formerly IAFE) and the Thalesians. The goal of the series is to provide a forum for the exchange of new ideas and results related to the field of quantitative finance. This goal is accomplished by hosting seminars where leading practitioners and academics present new work, and following the seminars with a reception to facilitate further interaction and discussion. The seminar series is limited to IAQF and Thalesians members only.
